The CAELinux Team is proud to release its new stable version of CAELinux, named CAELinux 2011.


This release is built on an updated Ubuntu 10.04.3 LTS  64 bit base with a focus on the upgrade of the CAE softwares and the addition of tutorials & wizards to make your first steps easier.

CAELinux 2011 contains the latest release of the Salome_Meca 2011.2 package developed by EDF (64bit) integrated with  two versions of the finite element solver for non-linear mechanics Code-Aster STA11.0 (both 64bits) optimized either for OpenMP or MPI parallelism. Salome_Meca 2011.2 is now based on Salome  v6.3 CAD/Pre/Post GUI and allows to run a complete FEA study directly from the SALOME graphical user interface.

CAELinux 2011 also continues to integrate great open source CFD software like Code-Saturne 2.0.2 and OpenFOAM 2.0.1 (both 64bit with MPI support) that can be interfaced with numerous pre processing tools like Salome, GMSH, Netgen, and the more CFD oriented meshers enGrid 1.2 and Discretizer/SnappyHexMesh. CAELinux 2011 now integrates two simple CFD Wizards to setup a a Code-Saturne or OpenFOAM study  from a mesh prepared in Salome. With these software, Open-Source FEA & CFD is continuing its progression towards ease of use and parallel computing power to get closer to commercial FEA & CFD codes!

Multiphysics simulation is also very efficiently carried out  using Elmer FEM 6.2 (64bit, with MPI & Mumps solver support) and its easy to use ElmerGUI interface. Based on a segregated solver approach for each physics, multiple physical behaviours can easily be coupled with Elmer, for example like: diffusion & heat equation can easily be coupled with Navier-Stokes fluid flow simulation, thermo-mechanical coupling and even fluid-structure interaction.

  • Is provided with video tutorials as well as examples to start learning how to use the included open-source softwares for realistic simulation
  • Ubuntu 10.04.3 already includes open-source 3D drivers for most of the video cards, but it can also automatically install packages for 3D accelerated proprietary video drivers (ATI & NVidia cards) once installed on hard disk.
  • This new release is only available as a LiveDVD ISO image to use directly from DVD, to be installed to USB Flash disk or to install the CAELinux OS on your computer for optimum performance. However, on recent CPUs with hardware virtualization extensions, it runs also very well in Virtual Machine software like VirtualBox or VMWare.

CAELinux 2011 LiveDVD


CAELinux 2011 is only available in 64bit version, this means that you will absolutelly need an X86_64 compatible CPU to run this version. Most recent Intel and AMD CPUS are 64 bit : for example Intel Core2Duo or Core2Quad, Core i3, i5, i7 and XEON 64 bit or AMD Athlon 64, Athlon X2, Athlon FX, Phenom, and Opteron. Please note that most Intel CoreDuo (not Core2Duo), Atom and Pentium 4 are NOT 64 bit compatible! Please check your hardware compatibilty first!! Using a 64 bit OS is necessary to use more than 2Gb RAM per application and thus allows for large "industrial scale" simulation capabilities. If your CPU is not 64 bit, you can still use our previous release CAELinux 2008 which is available in both LiveDVD and VMWare virtual machine version: see this page for more information on CAELinux 2008.

This LiveDVD distribution is highly compressed on the DVD and requires that the system decompresses all the necessary softwares into RAM in order to run. In LiveDVD mode, a minimum of 1024Mb is recommended to use this distribution for simple analysis. But you can create a Linux swap partition on one hard disk to help or choose the option to install the distribution to hard disk for optimal performance. However, 3Gb of RAM (or more) is highly recommended for every day work. An hard-disk installation of CAELinux 2011 requires at least a 20Gb ext3/4 partition for "/" and a 4Gb swap partition. At the moment most of the classical chipsets for Intel and AMD platforms are supported with some exceptions especially concerning the latest Intel Sandy Bridge and NVidia Optimus graphics adapters and some specific laptop devices (some wireless network cards) and very specific hardware like Raid controllers. For more help on hardware support / detection / troubleshooting, you should refer to the great Ubuntu documentation, wikis and  forums :


  1. First, download the ISO image from the link below. Then you should check the md5sum of your downloaded file to check if it is not corrupt: in Linux, use the "md5sum" command in a console, in Windows, you should download the "md5sum.exe" command line utility from here.
  2. Burn the ISO image on a DVD+/-R/RW with your favorite DVD burner software. Be sure to select the "Burn Image" option in your DVD burning software. If unsure, read the help of your DVD burning software. Alternativelly, you can install the LiveDVD on a USB key with the simple and efficient tool UNetBootin available here:
  3. Read the "Ubuntu Installation Manual " and associated documentation at
  4. Restart your PC, insert the LiveDVD (or USB key) and verify that your BIOS is configured to boot from CD/DVD drive (resp. USB external drive).
  5. Boot from the LiveDVD: you will see a prompt, Press ENTER and then a boot menu will appear with several options. Usually you don't need to select any special option here but if you have some problems during the boot process, some alternative options can be selected. For the moment, just press "Enter" to accept the default mode.
  6. When the GNOME desktop is finally loaded, you can start your work as if you were running from an hard disk. Note that all the readable partitions of your HDD will be allready accessible and your USB key or external HDD will be recognized when you plugin it in (read-write access).
  7. Now you can start your first tutorial on FE modelling with Salome_Meca: just click the "GettingStared" link on the desktop and follow the first tutorial on the FE analysis of a 2-stroke engine piston (from a STEP CAD geometry).
  8. If you are happy with the distribution, you can then install it to hard disk. The installer can even resize Windows or Linux partitions to free up some space and install CAELinux in parallel to your existing OS.


For the moment, a first documentation is available in the GettingStart.html  & "Ubuntu Installation Manual "  file included in the distribution. Several tutorials, videos and examples are included on the distribution and also downloadable on the wiki
